摘要

文章探讨了浮子阵列与抛物面防波堤集成系统的性能,旨在通过在抛物面防波堤前策略性地布置浮子阵列,最大化波浪能的利用。通过计算流体力学(CFD)方法,比较了开阔海域中单浮子、直线浮子阵列和基于理论自由表面次峰线的弧形浮子阵列性能,以及它们与抛物面防波堤集成后的效果。结果表明,直线阵列在开阔海域中表现更优,而基于理论自由表面次峰线的弧形浮子阵列在与抛物面防波堤集成后显著提高了发电效率。优化后的弧形阵列,相较于开阔海域条件下的发电功率提高了3.32倍,相较于直线阵列-防波堤系统提高了1.32倍。文章为波浪能开发提供了切实可行的方案,并为集成系统的进一步优化提供了支持。

Abstract

This study investigates the performance of an integrated system combining wave energy converter (WEC) arrays with parabolic breakwaters. The research focuses on optimizing wave energy utilization through strategic spatial arrangement of buoy arrays relative to parabolic breakwaters.  Computational fluid dynamics (CFD) method were conducted to compare the performance of linear and arc-shaped buoy arrays in both open water and integrated with parabolic breakwaters. The results indicate that while linear arrays are more effective in open water, arc-shaped arrays, when integrated with parabolic breakwaters, significantly enhance power generation efficiency. Specifically, the arc-shaped array optimally aligned with theoretically predicted secondary wave crest lines at 0.5 wavelength distance from the breakwater focus demonstrated a 3.32-fold increase in power output compared to open-water linear arrays, and a 1.32-fold improvement relative to linear array-breakwater integrated systems. This study provides a practical solution for wave energy development and offers insights for further optimizing integrated WEC and breakwater systems.
